Hi.
To get full scan on the 950 Lopt I connected the coils to the 405 & 625 tags this is a very low impedance winding and seems to match the 9-90 coils with only a slight increase of width on the left, on 405 the line timebase requires 110v HT to the lopt, 180 & 240 only require 75 & 82v for the same width and EHT of 8.5kv. So as can be seen the efficiency is actually greater than with the old TV22 scan coils.
On 405 lines the picture is stunning, very bright and good focus even on peak white. Far superior than in a TV9-90. A brilliant mod and so easy to do.
I intend to try 625 & 819 lines as well.
